Brianna and Amy decided to go for a hike for a couple days. As they started packing their back packs, Brianna read the things off a list of what Amy needed to pack — Water, food, pajamas, sleeping bag, and a tent. After Brianna finished packing, Brianna and Amy put on their packs and started hiking. When they had been hiking for about ten minutes and were starting to climb up a big mountain with a steep slope, Brianna said to Amy,” Hmmm, it seems like I’m missing something. Now, what do I need?” Then all of a sudden she remembered. “My camera!!!” she exclaimed.
